This new retaining flange is made of worked aluminium and incorporates two countersinks and grooves for holding the chassis in place. The set also incorporates the necessary screws with plastic configuration. All of these features reduce the movement in the rear track of this new and exciting Mini-Z MR03 by Kyosho. The assembly instructions are very simple; the flap has two positions, but it also can be mounted using two additional positions which is what makes it compatible for use on Mini-Z 94mm, 98mm and 102mm cars. As you can observe in the graph, with this part you can set up 3 different configurations. It´s also worthwhile to note that the aluminium plate is designed so that the screw can enter perfectly into the aluminium without pertruding and therefore does not interfere with the carbon or fiber «T».
